i Le n a me" , b, <starting address> , <length in bytes>
[ , <optional entry point> ] [RETURN]
This option allows you to perform a binary save where a complete block of data in the
computer's RAM is stored onto disc exactly as it occurs in the memory. It is necessary
to instruct the computer where the section of memory you need to save starts, how
long it is, and if required, the memory address at which to start execution should the
file be run as a program.

onto disc in the form of a screen dump. The contents ofthe screen will be saved exactly

ern dum p" , b , 491 5 2 , 1 6384 [RETURN]
.... where 49152 is the starting address of the screen memory, and 16384 is the
length of the screen memory that you wish to save.
To call it back onto the screen, type in:
Loa d "s ern dum p" [RETURN]
